Prof. J. McKim Malville thinks that the Pueblo Indians observed the "lunar standstill" at Chimney Rock. As written in the article, "Trekkers eager to be moonstruck: Ruins on Colo. mesa offer view of lunar standstill", by Electa Draper, Denver Post Staff Writer:
"Every 18.61 years, the moon completes a great sweep across the sky until moonrise finally occurs at the northernmost point of the lunar journey along the horizon. This astronomical event lasts almost four years."Written there also is:
"Archaeologists believe this special purpose for Chimney Rock was lost until rediscovered in 1988 by University of Colorado professor J. McKim Malville."For once, we agree with a mainstream archaeologist. Malville is surely right.
This 18.61 year cycle was known in ancient Babylon as the Saros Cycle.
This 18.61 year cycle is also found in the United Kingdom marked by the 56 Aubrey Holes at Stonehenge (18.61 x3), which can be used to predict eclipses.
